Before you begin using an equal arm balance, you must make sure the riders are an equal distance apart, and make sure the balance is balanced. Then, place the object(s) on one side of the balance, and the object(s) that you want to compare them to. Whichever object is closer to the ground is heavier. If the objects are equally levelled, they have equal mass.

Two pans of equal balances are placed at the end of the beam, one at each end. A long pointer attached at right angles to the beam at the point of support. Zero on a scale incates the beam is at rest.

An equal arm balance can be used to weigh or compare objects with a high degree of accuracy. The arms must be properly calibrated to equal lengths and balanced evenly on the axis of rotation prior to use.

Equal arm balances are recommended for laboratories, to weigh small amounts of materials. I believe that they are more exact.

The equal arm balance is used on a lever, in particular, the class 1 lever. It consists of a beam that pivots around a central point with two identical arms on either side for balancing weights on a fulcrum.
